Long Lasting, but Poor Dust Collection

March 20, 2015

Recommended Product

These sanding discs leave a great finish and work pretty well with my Hitachi 5" 8-hole sander. Right out of the box, I slapped one on my sander and went to work finishing a 20" x 24" sheet of plywood. The edges of the plywood had a bit of Polyshades residue on them that had dripped down when I finished the top. I was expecting the discs to have a hard time with this, but they didn't gum up at all! The end result was a smooth, stain-ready surface.
The hook and loop backing can handle being removed and applied several times without any adverse affects on its adhesion. The discs last a long time and really hold onto their grit too. They're also pretty reasonably priced for a name-brand product when bought in the bulk 50-pack. Diablo definitely hit it out of the park on durability and performance with these.
However, I do have one complaint. The "universal" hole design doesn't seem to allow my sander to collect as much dust as with a standard 8-hole disc. I noticed a slight dust cloud building up while using them the first time, and decided to run a few back to back tests with another brand of 220 grit discs that have an 8-hole configuration. Sure enough, running a new disc of the other brand resulted in the sander collecting almost all of the resulting dust. So either the Diablo discs are so good that they remove stock that much faster (unlikely), or they don't allow the sander to get sufficient air flow through the holes. This makes sense, since the "universal" hole configuration has nearly 40% less hole area than the standard 8 hole configuration.
So in conclusion, these are great sanding discs with the exception of dust collection. If Diablo came out with separate 5-hole and 8-hole discs, they'd get 5 stars from me.
